I have two 30gal propane tanks according to the manual they hold 7 gals each at 4.3 lbs a gal. Why does a 30gal tank hold 7gals?
thanks

I answered this question on the other thread. 7 gallons x 4.3 lbs/gallon = 30.1 pounds. That's pretty close for a 30 pound cylinder.

Okay, that makes sense in most worlds. It does create another issue. I paid 22USD to have it filled and thought I was doing great for 30gals of propane but now that I know I only got 6gals of propane it doesn't seem like that great of a deal.

I own a campground. I have pumped more propane than I care to remember. A 30 lb tank when completely empty holds 7.2 gallons.

A 20 lb tank hold 4.7 gallons.

Propane is differently priced all over. Being in New York which is typically higher than most states, I charge $18 for a 30 lb tank. And that is a "convenience" price.

I do believe you got ripped off.

You should also note that to be able to dispense by the gallon, the pumper has to have a special certification and more inspections. I am allowed to only charge by the size tank, empty or not. Of course, I can tell you I always treat my customers right.

I try to take my tanks to a Flying J when it's feasible, they meter it into the bottle and their current price is $1.99 per gallon along the route I recently traveled. They also give a $.05/gal discount if you have the RV'rs discount card.

A 7 gallon (30# bottle) filled at a Flying J will run me about $13.58, much better than the $20 my local propane distributer charges. Also, if there's a gallon or so still in the tank, my local distributer will still charge the full amount.

Good deal for him; not so good for me.

We needed to fill our 20lb tanks and went looking for a refill. Only place we could find that was willing to get off their lazy butt wanted $22 (Arrowhead across from the Ga Vets SP entrance). Hauled the tanks into Home Depot and swapped them out for $17 (Amerigas). Our permanent-mount RV tank will remain empty until we can get a better price. Good thing we set up the gas lines to use the little BBQ tanks. Also confirmed decision to use only 20lb-ers in the bus conversion (cooking fuel only). Just seems to me that a swap should cost more than a refill! But which ever is the cheaper will work for me!
